STEEL CONSTRUCTION,

I SPECIFICATION forming part of Letters Patent No. 691,531, dated January 21, 1902.

Application filed J'uly 12, 1901.

To @ZZ whom, it may concern;

Be it known that I, HARRY C. CLARK,a citizen of the United States of America, residing at Belleview, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Steel Constructions, of which the following is a specification, reference being had therein to thev accompanying drawings.

This invention relates to certain new and useful improvements in steel, iron, and Wood constructions, and relates more particularly to the clamps forming the connection between the I-beams andchannels, wood, iron, or steel beams, but can be advantageously employed in connection with I-beams, T- beams, steel braces, channel-bars, and other forms of steel and wood constructions.

The present invention is particularly designed to be employed in connection with steel, iron, and wood constructions for buildings and the like; but I di) not wish to limit myself to this particular use, as I nd the invention affords great advantages when attached to rails or employed in connection with steel constructions of bridges and like structures.

The invention consists principally in the novel clamp employed for connecting beams together; and the invention still further consists inthe novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

' In describing the invention in detail reference is had to the accompanyingldrawings, forming a part of this specication, wherein like numerals of reference indicate corresponding parts throughout the several views, and in which- Figure 1 is a perspective view of a pair of I-beams and channel-bar connected thereto, showing my clamps applied in position. Fig. 2 is an end view thereof. Fig. 3 is a detail perspective view of one of the clamps. Fig. 4 is a modification of my improved clamp.

In the drawings the reference-numeral 1 indicates a pair of I-beams having arranged on the base thereof my improved clamp, which consists of a top portion 2, bent upon itself and forming an inwardly-extending Serial No. 68,012. No model.)

yThe reference-numeral14 represen ts a nut secured upon the screw-threaded portion upon the other end of the bolt.

The reference-numeral 15 represents a bar whichis arranged in the opening 7 and is passed through the opening 6.

The numeral 15 represents the ceiling as having securing-slits 16, by which the ceiling is fastened to bars l5 by wires 17 passed therethrough.

The operation of my improved device is a follows: The I-beams or other form of beams are engaged by their base by the clamp portion 4 and fiange 3, the securing-bolt clamping the other end of the beam, which is tightened by means of the nut 14. The bar may be easily placed in position by passing the same through the opening 6 and seating it in the opening` 7 of the clamp, thereby resting it upon the base 9. The advantages of this construction will be readily apparent, as it willbe seen that the bar may be easily applied to the clamps without the necessity of placing it into position endwise through the clamps, but allowing it to pass over the upwardly-extending portion 8 through the opening 6 into the opening 7, as heretofore described.

In case it is desired to further lower the channel-bar than shown in Figs, 1 and 2 the hanger 16, as shown in the modified form in Fig. 4, may be employed, this hanger being secured in the opening 7 of the clamp, and for this purpose hangers of different lengths may be employed. The inwardly-extending ange 3 is preferably constructed in one piece, not bent over upon itself, as shown in the drawings, but formed solid with the body portion ICO of the clamp, as shown in Fig. 4 of the drawings. By this construction I also dispense with the second clamp, which has heretofore' been employed, thereby materially lesseniug the cost of this form of construction.

The many advantages obtained by the use of my improved clamp will be readily apparent from the foregoing description, taken in connection with the accompanying drawlngs.

Itwill be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having f ull y described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a steel, or iron construction, the combination of beams, a clamp consisting of a clamp portion, a bolt passing through said clamp portion, the end of said bolt engaging the other side of said beams, said clamp having an opening and a bar arranged in said opening.

2. In steel or iron construction, the combination with beams, of a clamp secured to one side of said beam, said clamp having a portion thereof bent upon itself upon which said beam rests, a bolt secured to said clamp with its other end engaging the other side of said beam, the said clamp having an opening formed therein, and a bar arranged in said opening, substantially as described.

3. In a steel, or iron construction, the combination of beams, clamps arranged to one side of said beams having an upwardly-extending portion With an opening formed in said upwardly-extending portion, bars arranged therein, an inwardly-extending ange arranged on said clamp, a bolt extending through said clamp engaging the other side of said beams, and a nut secured to said bolt, substantially as described.

4. In steel or iron construction, the combination with beams, of a clamp secured to one side thereof, said clamp having its ends bent inwardly and being doubled upon itself at an intermediate point, the said beam engaging said doubled portion and one of said ends, a bolt engaging said clamp and said beam, the said clamp having an opening formed therein extending to the other of said inwardlybent ends, and a bar carried by said end, substantially as described.

5. In steel or iron'construction, the combination with beams, of a clamp secured to one side thereof, said clamp having an inwardlybent end and a portion bent over upon itself between which -end and bent-over portion said beam is secured, a bolt secured to said clamp and engaging the other side of said beam, said clamp having a downwardly-extending portion, and a bar carried by said downwardly-extending portion, substantially as described.

6. In steel or iron construction, a clamp having inwardly-extending ends and an intermediate portion of itself doubled to form an inwardly-extending portion between which and one of said ends ya beam is secured, the said clamp having a vertical and a horizontal opening formed thereon, and a bar carried by said other end of the clamp, substantially as described.

7. In steel or iron construction, a clamp which has a portion bent over upon itself and an inwardly-extending end between which end and bent-over portion a beam is adapted to be secured, the said clamp further having a downwardly-extending apertured portion, and a bar carried by said downwardly-extending portion, substantially as described.

S. In steel or iron construction, the combination with a beam, of a clamp comprising inwardly-extending ends and a portion bent over upon itself suitably secured to said beam and a bar carriedgby one of said ends, substantially as described.

9. In steel or iron construction, the combination with a beam, of a clamp arranged on one side of said beam, a bolt engaging said clamp and extending parallel with the base of said beam and its end engaging the other side thereof, a base made integral with said clamp, and a bar carried by said base, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
